Specification of Letters Patent.

Application filed October 21, 1820. Serial No. 418,367.

To all whom it may concern:

Be it known that we, GEORGE E. QUIMBY and HORACE F. PARKER, citizens of the United States, and residents of Bondsville, in the county of Hampden and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Belt- Shippers, of which the following is aspecification.

Our invention relates to improvements in belt shipping devices employed on machines having tight and loose pulleys in combina tion with a belt for the transmission of power. The invention is especially applicable to machines having an excessive starting torque due to overcoming the inertia of rotating members. In machines of this kind the belt, unless excessively tight, is apt to slip when being shifted from the loose to the tight pulley. ccordingly the operative customarily facilitates the starting of the machine by exerting pressure with his hand against the belt thus laying himself liable to more or less serious injury. It is accordingly proposed in the present invention to produce an improved belt shipping mechanism that will eliminate all liability of injury to the operative.

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

Referring to the accompanying drawings, Figure 1 is a side elevation of a portion of a carding machine, showing our belt shifting device and its relation to the driving pulleys of the machine; Fig. 2 is a plan view of the same; Fig. 3 is a side elevation of shipper in operative action on the belt; Flg. 4c is an end elevation of Fig. 3; Fig. 5 is a partially sectional view of the shipping rod and clutching means.

In the drawings 1 and 2 are the tight and loose pulleys respectively, mounted on the shaft 3, 4: is the driving belt, 5 1s a bracket secured to a stationary part of the machine on which the hanger 6 holding our improved belt shipping device is adjustably mounted. From the lower part of the hanger 6 the slideway 7 extends horizontally above the faces of the pulleys and supports the belt slide 8 provided'with ears 9 which serve as holders for the belt guiding fingers 10. The binding pulley 11 is journaled in a holder 12 which is slidably mounted in the slots 130i? the belt guide fingers 10. The binder pulley is normally held out of contact with the belt by means of the springs 14 exerting tension between the pulley holder 12 and a stationary part of belt guiding frame.

Movement is imparted to the belt slide 8 through the crank and link connection 15 by means of a rock-shaft 16 which is mounted in bearings 21 secured to the top of the hanger 6, the shaft having a short longitudinal movement limited by the collars 17 and 1S fixedly secured to the shaft. The crank above mentioned is secured to shaft by a sliding key 24. A half turn of the shaft shifts the belt completely from one pulley to the other. At an intermediate point on said shaft an arm 19 is loosely mounted. Clutch engaging means are provided between the hub of this arm and the collar 17 secured to the rock-shaft. Normally the clutch is in a disengaged position owing to the compression spring 20 mounted on the rock-shaft between the collar 17 and the hub of arm 19.

The arm 19 is flexibly connected to a cam shaped lever 22 pivotally mounted on the belt guide fingers which acts in conjunction with a shoe 23 on the binder pulley holder to force the pulley into a binding relation with the belt.

In operation, the machine being at a standstill with the belt on the loose pulley, the operative gives a half turn to the hand wheel 28 on the end of the rock-shaft and at the same time pushes the shaft longitudinally so that the clutch members of 17 and 19 engage causing the arm 19 to actuate the cam lever and thus forcing the binding pulley into contact with the belt and accelerating the start of the machine. The pressure on the rock-shaft may be released if desired by the operative before the belt is completely on the tight pulley. With the release of the pressure the clutch members are disengaged and the binder pulley is drawn out of contact with the belt by the springs 14.

Having described our invention, what we claim and desire to secure by United States Letters Patent, is

. 1. In combination, a driving shaft, a pair of tight and loose pulleys, a belt, a bracket mounted on a stationary part of the machine, sliding ways on the bracket extending across the faces of the pulleys, a sliding member supported on the Ways, belt guiding fingers attached to the slide, a belt binding member adj ustably supported by the slide, means for normally maintaining the belt binding member out of contact with the belt, means for forcing the'belt binding member into contact with the belt, a manuallyoperated shaft for reciprocating the slide transversely across the faces of the pulleys, an arm on the shaft,

connections between the arm and belt binding actuating means whereby motion imparted to the shaft creates a binding action on the belt. 7 r

2. In combination, a driving shaft, a pair of tight and loose pulleys, a belt, a bracket mounted on a stationary part of the machine, sliding ways on the bracket extending across the faces of the pulleys, a sliding member supported on the ways, a frame embracing the belt and attached to the slide, a binding pulley boxed in the frame and slidably m0vable therein, flexible means for normally maintaining the binding pulley out of contact with the belt, means comprising a cam shaped lever for-forcing the binder pulley into contact with the belt, a manually operated shaft, an arm loosely mounted on the shaft, clutching means betweenthe shaft and arm and connections between the arm and cam lever.

In testimony whereof we have signed this specification.
